推荐答案

每个目录的开头都有两个条目，名称分别为.(指向自身的链接)和..(指向其父目录的链接) ).当然，例外是根目录，其中..目录也指的是根目录.

Each directory has two entries in it at the start, with names . (a link to itself) and .. (a link to its parent directory). The exception, of course, is the root directory, where the .. directory also refers to the root directory.
